Project description:Gene expression and H3K27 tri-methylation analysis of meristematic tissue (Me) and young leaves (Le) isolated by manual dissection of clv3-9 plants
Project description:For the histone methylation analysis of undifferentiated and differentiated tissues a meristem enriched fraction and young leaves (up to 3 mm leaf blade length) were isolated from clavata3-9 plants. Clavata3-9 mutants harbour larger shoot apical meristems than wild type plants enabling the preparation of meristematic tissue by manual dissection. Samples from both tissues were used for expression and histone H3 lysine 27 trimethylation (H3K27me3) analysis. Tissues for expression and H3K27me3 ChIP-chip analyses were simultaneously harvested.

Meristem enriched samples (Me1 and Me2) and young leaf samples (Le1 and Le2) of clavata3-9 plants were isolated and hybridised to whole genome tiling arrays [platform GPL3371]. Two biological replicates were performed.

Samples from both tissues were used for expression and histone H3 lysine 27 trimethylation (H3K27me3) analysis. Tissues for expression and H3K27me3 ChIP-chip analyses were simultaneously harvested. Meristem enriched samples (XMe1 and XMe2) and young leaf samples (XLe1 and XLe2) of clavata3-9 plants were isolated and hybridised to Agilent 44 k arrays [G2519F, V4 (Agilent, Santa Clara)]. Two biological replicates were performed.
Project description:We isolated the meristematic and elongation zones of Col-0, upb1-1 mutant and 35S::UPB1-3YFP/upb1-1 plants by micro-dissection and extracted RNA from each section independently. To identify genes that might mediate UPB1 function we conducted a series of microarray experiments. The spatial distribution of the UPB1 protein suggested that it might exert a different effect on gene expression in the meristematic and elongation zones. Therefore, we isolated the meristematic and elongation zones by micro-dissection and extracted RNA from each section independently.

The spatial distribution of the UPB1 protein suggested that it might exert a different effect on gene expression in the meristematic and elongation zones. Therefore, we isolated the meristematic and elongation zones by micro-dissection and extracted RNA from each section independently. Total RNA was isolated from approximately 60 meristem- and elongation zones of Col-0, upb1-1 and 35S::UPB1-3YFP #2 6 day old plants. Two biological replicates were performed for each experiment.
Project description:ra03-02_potyvirus - potyvirus - Identification of genes involved in plant/virus interactions. - In this experiment, Arabidopsis plants infected by a virus, Tobacco etch virus (TEV), a potyvirus, were compared with healthy plants to identify genes for which the expression is modified by the viral infection. Analysis of both inoculated leaves and upper young leaves were performed 7 days after the inoculation with the virus (or with only buffer for the healthy plants). Keywords: normal vs disease comparison
